I am the second owner of a 2005 Fleetwood Southwind. I suspect there is some sludge or grease buildup that causes the gray tank to drain slowly. Can anyone recommend something to break it up?
I don't use anything and never have a problem, but if I had a grease buildup problem, I'd keep some laundry detergent in the tank. Maybe if you'd use some dish detergent when washing dishes ??? Oh, but for the problem, I'd shove a running garden hose up there.....where the sun don't shine ? :)
